Somewhat surprisingly, the 20-year-old third baseman did not have a double in Tuesday night's 9-3 loss to the Washington Nationals. But Machado had hit five doubles in the five previous games, raising his season total to a league-leading 23 doubles, four more than Boston's Mike Napoli. With 23 doubles in 52 games, Machado is on pace to hit 72 over a 162-game season, which would break Earl Webb's all-time record of 67 doubles in a single season. Sustaining that pace won't be easy for Machado, though. No major league player has smacked 60 doubles in a season in more than 70 years. Brian Roberts came close with 56 doubles in 2009.
